The Rhinestone Cowboy, Glen Campbell, has been forced to cancel his Australian tour dates with Kenny Rogers. The Gympie Times reports that Campbell pulled out due to illness and believes his Alzheimer’s has progressed to a point where he is unfit for travel.

Replacements for next month’s shows include Australian country music stars John Williamson, Beccy Cole, Lee Kernaghan, Troy Cassar-Daley and Sara Storer. These replacements were announced on Kenny Rogers’ official website and he did not want to speak about Campbell’s tour absence during an interview.

The news of Campbell’s Alzheimer’s came back in June 2011, also with the announcement of his final Album (Ghost on the Canvas) and his Goodbye tour.

Just this week, Campbell released a music video for the song “A Better Place.” It is a farewell video that features Campbell looking back at his life and career. The video also includes a personal message to his fans and his wife Kimberly. “My love goes out to Kim, my amazing grace. You’ve been by my side through these changing times, and it means the world to me.”
